Albumin in Acute Ischemic Stroke Trial

Phase 3TerminatedNCT00235495

University of Miami841 enrolled

Overview

The goal of the trial is to determine whether human albumin, administered within 5 hours of symptom onset, improves the 3-month outcome of subjects with acute ischemic stroke.

Human serum albumin, at 2 g/kg, administered over 2 hours by intravenous infusion, will be compared to placebo (isovolumic normal saline) among patients with acute ischemic stroke. All patients will have a baseline stroke severity measured as NIH Stroke scale score \> 5. Patients will treated according to the best standard of care including concurrent treatment with intravenous or intra-arterial thrombolysis where appropriate. The primary outcome will be determined at 3 months. The primary hypothesis is that, using the composite outcome of a modified Rankin score 0-1 or NIH stroke scale score 0-1 at 3 months (or both), the proportion of patients with improved outcomes will be greater by 10% or more in the active treatment group. \[The current trial is termed "Part 2" and incorporates revisions to the initial protocol that were instituted after the Data Safety Monitoring Board (DSMB) suspended subject recruitment because of a safety concern after 434 subjects had been enrolled. The protocol revisions of Part 2 resulted from the study team's thorough review of the Part-1 safety data and were designed to optimize safety going forward.\]

Patients who live in a nursing home or who are not fully independent for activities of daily living immediately prior to the stroke are not eligible for the trial. * In-patient stroke. I.e., patients with a stroke occurring as a complication of hospitalization for another condition, or as a complication of a procedure. * Planned acute use of intra-arterial (IA) tPA or acute endovascular intervention (e.g., stenting, angioplasty, thrombus retrieval device use) must conform to the following criteria: (1) begin within 5 hours of symptom onset, and (2) finish within 7 hours of symptom-onset. * Fever, defined as core body temperature \> 37.5° C (99.5°F). * Serum creatinine \> 2.0 mg/dL or 180 µmol/L. * Profound dehydration. * Evidence of intracranial hemorrhage (intracerebral hematoma (ICH), subarachnoid hemorrhage (SAH), epidural hemorrhage, acute or chronic subdural hematoma (SDH)) on the baseline CT or MRI scan. * History of allergy to albumin. * History of latex rubber allergy. * Severe chronic anemia with Hgb \< 7.5 g/dL * Pregnancy, breastfeeding or positive pregnancy test. (Women of childbearing age must have a negative pregnancy test prior to ALB administration.) * Concurrent participation in any other therapeutic clinical trial. * Evidence of any other major life-threatening or serious medical condition that would prevent completion of 3-month follow-up, impair the assessment of outcome, or in which ALB therapy would be contraindicated or might cause harm to the subject.

Outcomes

Primary Outcomes

The Number of Participants With Favorable Outcome Defined as National Institute of Health Stroke Scale (NIHSS) Score of 0-1 and/or Modified Rankin Scale (mRS) of 0-1.

The National Institutes of Health Stroke Scale (NIHSS) is a systematic assessment tool that provides a quantitative measure of stroke-related neurologic deficit. The scores range from 0 to 42 with a score of greater than 20 indicating severe neurologic deficit. The mRS ranges from 0-6 representing perfect health without symptoms to death. A score of 0 is no symptoms at all and a score of 1 is no significant disability. Able to carry out all usual duties and activities.

Time frame: at 3 months

Secondary Outcomes

Number of Participants With a Composite Outcome of mRS 0-1 and/or NIHSS 0-1 and/or Decrease in NIHSS From Baseline by 10 or More Points

Time frame: at 3 months

Number of Participants With a NIHSS of 0-1 at 24 Hours

Time frame: at 24 hours

Number of Participants With a NIHSS 0-1 at 90 Days.

Time frame: at 90 days

The Number of Participants With a Score on the mRS 0-1 at 90 Days.

The mRS ranges from 0-6 representing perfect health without symptoms to death. 0 = No symptoms at all. 1 = No significant disability. Able to carry out all usual duties and activities. 2 = Slight disability. Unable to carry out all previous activities but able to look after own affairs without assistance. 3 = Moderate disability. Requires some help, but able to walk unassisted. 4 = Moderately severe disability. Unable to walk unassisted and unable to attend to own bodily needs without assistance. 5 = Severe disability. Bedridden, incontinent, and requires constant nursing care and attention. 6 = Dead.

Barthel Index (BI) 95-100

The Barthel Index (BI) is an ordinal scale used to measure a subject's performance in activities of daily living (ADL) in ten variables - feeding, transfer (bed to chair), grooming, toilet use, bathing, mobility on a level surface, stair use, dressing, bowels and bladder. It is an assessment of independence in ADL and is scored in increments of 5 points. the highest total score for fully independent subjects equals 100. A higher number is associated with a greater likelihood of being able to live at home with a degree of independence.

Time frame: at 90 days

Number of Participants With an EuroQol (EQ-5D) Favorable Score < 0.78

The EQ-5D measures the subject's overall health state in a descriptive system of health-related quality of life (QoL) states consisting of five dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) each of which can take one of three responses. The responses record three levels of severity ('no problems', 'some problems', and 'extreme problems) within a particular EQ-5D dimension. The EQ-5D results can be converted to health utility scores.

Number of Participants With a Stroke Specific Quality of Life Scale (SSQOL) Score of >=3

Stroke, specific, health-related quality of life (SSQoL) is a self-reported survey that includes 12 domains and 49 items which are scored on a 5pt Likert response format with a lower score indicating worse function/lower ability on that item or domain. Domain scores were calculated as an unweighted average of item scores in that domain. Overall Total Score was calculated as an unweighted average of domain scores. Each Domain Score and the Overall Total Score all range from 1-5 with 1 being worst and 5 being the best. We have presented data here for the number of participants that have an unweighted average of domain scores of 3 or greater.

Trailmaking A

The Trail Making Test is a neuropsychological test of visual attention and task switching that is thought to be sensitive to the presence of cerebral dysfunction. It is a timed test consisting of two parts where the subject is asked to draw a "trail" made by connecting numbers in sequential order (part A) and then in part B the combination of numbers and letters. Scoring is calculated separately for Parts A and B but both scores are provided as the minutes and seconds it takes for the subject to complete ach part. Normally, the entire test (A and B) can be completed in 5-10 minutes.
